Hey that second screenshot is so cool! How did you manage to get BAR1 on your MAC? What command did you use?I will have a look to see why it's not working, but I may need some more screenshots from you (look at the screenshots by Felix Chan in the other brightness thread)

That screenshot is from RWEverything from windows when I saved as plane text just to show the value. What else do you need?

You guys need to check your installation because it is not normal to get these chirp sounds or coil sounds on your computer. You sure its not the HDD that makes these sounds? Well sometimes you will hear clicks but that is normal because OS X is reading the disk.

As for my SSDT, I attached it here but you cannot use it. You need to create your own.

Everything working fine, but how can i change this "Uknown" os-info to correct "Intel HD Graphics"?8086004602

I haven't added this information either in my guide (at one point I will) but all you have to go is add your Intel HD Graphics information under GFX0 in your DSDT. Basically you use a DSM method in there.

Well coil whine is "normal" if there is too much power load on coils, i.e. bad power managementAnd i'm pretty sure its not my HDD cos i dont have a HDD I do use SSDT thoughIn early macbooks, the coil noise was present and could be removed by a work around by disabling C4 state, but that decreased battery life so it was never an ideal workaround. People made apps such as ShhMBP to remove the noise, but all those apps had side effects. I wonder if its worth trying those apps out

This sound existed prior to frame buffer, so i doubt its the culprit, try different resolutions i have a feeling a single link lane on x1 width is just to much stress on the gfx........

example in linux i'm using a single link with x4 width ,but that config don't work under framebuffer.

This is Close to some power issue,like frequency voltage or something

For now check temps make sure nothing is over heating as this happens when the gfx receives a work load whether small or big.

are you saying using a dual link fb instead of single link could possibly help ?

pentothal I think I have an idea: I remember you were having trouble with your EDID with the resolution module, and RemC helped you with it, hard-coding it to use your "magical" edid. However, the problem may not be because of the framebuffer not working, but rather it's picking up a weird EDID. Do you have networking set-up? If so, do you happen to be able to use VNC to see if the framebuffer's working? If it is, then try creating an override with this thread: http://www.insanelym...splay-problems/ This will override any faulty EDID and use the one that works for you. Work using Method B, and see if this fixes the problem. Be sure to use your "Magical" EDID.
